Influence on modern practice
Kaptchuk turned the placebo effect from a research nuisance into a field with its own Harvard programme, changing how trials are designed and how the clinical encounter is valued. His open-label placebo results are replicated in IBS, chronic low back pain and cancer-related fatigue, and are reshaping ethics guidance on placebo use.

Placebo as a measurable clinical phenomenon rather than a nuisance variable.
What modern research says
- EstablishedCheck the literature — PubMed ↗
Open-label placebo trials show symptom improvement in IBS, chronic low back pain and cancer-related fatigue even when patients know.
- EmergingCheck the literature — ClinicalTrials.gov ↗
Durability and generalisability beyond symptom-report outcomes remain open.
Clinical protocols
- Open-label placebo protocols in registered clinical trials
- Consultation-style components explicitly designed into trial arms
Real-world uses
- Clinician-communication training that treats context effects as therapeutic
- Regulatory debate over placebo-controlled trial design
